The Delaware & Hudson-Largest Roundhouse/turntable pre 1954

[Anonymous]

Im Looking for Info,specs,pics of the D&H 105'Turntable that was installed 1924 in Oneonta NY,have read many books but come up with the 75' 1 prior 1924. I am going to scratch build the turntable and need to know is 105' the pit or table lenght,how deep[ would pit be? Im modeling the D&Hs quote largest Roundhouse in the world till it was torndown in 1954 that is the focal point of my layout.

The depth of the 'pit' is going to depend on the size of the 'bridge'. Is there a photo that you can 'scale' from to get an idea?
BTW, 105' is a good size TT; but UP had at least 5 135' TT's and the NP had a 136' at Livingston, and the CB&Q had a 137' TT at Chicago. Anyone know of 'larger' ones?

The Pics i have are in a book by Jim Louden,the are dimensions on the 75' TT but not properly listed (for instance it says outside wall @ ringrail is 4'-4" and the center is 3'-6" Im assuming thats a misprint) Sizing the men up that are installing the TT in the pics lets assume avrage man is at least 5'-10" -the men standing next to the TT need another head lenght to come even w/ the top of the girder. If I measuer the men and take my # to the side of girder in pic -basicly same hight. The pics that i have are in a book-showing the stages of removel/install from 75/105'TT
